Specification of Letters Patent.

Patented Aug. 10, 1909.

Application-filed March 21, 1904. Serial No. 199,253.

To allwhom 'it may concern:

Be 1t known that I, JOHN M. MoKnRcHEY, residing at Detroit, in the county of Wayne and State of Michigamqa citizen of they United States, have invented certain newv and useful Improvements in Trap-Fittings, of which the following is a specification, reference being had therein to the accompanying drawings.

rlhe invention relates to trap fittings and consists in the peculiar construction, being more especially designed for use in connection with the formation of traps for outside closets. IIeretofore traps for this purpose have usually been formed by a number of separate fittings. Such constructions have various disadvantages, among which are, 1st, the difhculty in maintaining the several sections in proper relation to each other. 2nd, the danger of clogging and the difficulty of cleaning when once clogged. 3d, the insufficient support for the standpipe and consequent danger of settling. 4th, the time required in constructionv to properly assemble and secure the various 'fittings in relation to each other. Y

With the present inventionV these objections have been overcome by construction as hereinafter set forth. y

In the drawings, Figure l is a vertical, longitudinal section through the fitting. Fig. 2 is a plan View thereof. Fig. 3 is a horizontal section illustrating modification.

The fitting may be formed of any suitable material, but preferably of crock or tile. It, consists of a cylindrical Ybody portion A having a vertical axis, and the upper end being preferably provided with an enlarged flange a for connection with the standpipe, such as indicated in dotted lines at B. At one side of the body A is integral nipple C, which forms the inlet connection, the diameter of this connection being considerably less than the diameter of the body portion A.

D is the outlet connection, also preferably formed integral with the bodyA, and hav ing its opening in said body arranged below the level of the inlet connection C. The outlet D extends upward and at its upper end has the elbow E, which is preferably enlarged substantially in axial alinement with the nipple C.

With the construction described, the wall F which separates the chamber in the body A from the passage in the connection D pro,- jects downward a considerable depth below the water level which is maintained to the height of the bottom of the nipple C and elbowj E, thus forming an efficient water seal. The capacity of the outlet connection D is preferably substantially the same as that of the inlet nipple C, and both are con` lsiderably smaller than the body portion A.

The body portion A is preferably formed `with a flat base Z) which is of sufficient area to form a firm support for the fitting in the soil.

'Ihe fitting described may be used for the construction of an outdoor closet in which the standpipe B rises to the surface of the ground while the fitting with the inlet and outlet. connections C and D is arranged below the frost line. In construction the vfitting is placed in position with the base d firmly supported on the soil beneath, this base, being of considerable area and being arranged directly beneath the body section A which is connected with the standpipe, serves to form a firm support for said standpipe which will prevent settling. It also forms a straightway passage from the top of the standpipe to the lowest point in the trap, so that in the case of the lodging of cloggingmaterial in the trap it may be readily removed through the standpipe. Furthermore, on account of the large diame ter of the body portion A the velocity of the water current passing through the inlet C and the outlet D is greatly diminished in the body A, with the consequence that there is less danger of drawing solid material, which would tend to clog the trap, into the outlet connection D. While I have described the fitting as adapted for the one use, it is evident that it may have other uses to which it is equally applicable. Y

In Fig. 3 I have shown a modified construction in which the inlet nipple C connects tangentially to the body A, so that the water entering through said connection will be Vcaused to rotate around in the casing. This will facilitate the cleaningv of the fitting and it will also tend to prevent siphona e.

wWhat I claim that my invention is: l. A trap fitting comprising a vertically arranged cylindrical body portion open at its upper end and having a flat bottom, an integral inlet connection of lesser diameter than said body portion and arranged above the bottom thereof, an integral upturned established an integral upturned outlet connection also vof lesser diameter than said body communieating therewith radially at the bottom and discharging at a point to maintain the water level within the body below the top of the inlet connection whereby free air communi cation is established between the body portion and said inlet.

In testimony whereof I aiiix my signature yin presence of two witnesses.
